3.0C version only: Motor heating: the compartments in which the rocking and vibration motors are each contained must never exceed 50°C during operation. This must be met for an ambient environment of 25°C with little/no air movement. This must remain true for extreme use cases of most onerous loading condition of 9.0 kg test mass placed in the head or foot of the sleep area, for all rocking speed and vibration intensity settings, and for a test duration of 10.0 hours. Shorter test durations are acceptable if compartment temperatures reach steady state and show no signs further temperature rise would occur due to continued operation.
